Signal Blocking Guard Pouch Bag,Antitheft Lock

Detailed Information About The Product:

RFID signals block nano-shield materials to protect your car's security system from hackers. Protect your personal and financial data by preventing RFID scanners and card readers from detecting the card's RFID signals.
The car key case is divided into an inner layer and an outer layer. When pd in the inner layer, the signal can be completely shielded, preventing scanning and electronic information from leaking, and the cell phone signal can be blocked, thus putting the phone in a "sleep" state. The shielding band is: 10kHz-30GHz.
When pd in the outer layer, it can effectively shield electromagnetic radiation, and the shielding value reaches 90.999%, which is the best product for pregnant women.
It is a structure that blocks the passage of radio signals.
Modern keyless fobs carry identification chips that pick up radio signals sent out by their car. The vehicle recognizes the fob when it's in range and unlocks the doors. Keyless ignition systems work in the same way - enabling cars to start when the key fob is detected in the cabin.
Criminals can exploit this via a wireless relay attack. Using a radio frequency relay booster, it's possible to pick up and then transmit a key fob signal to trick the car into thinking a fob is present. This enables entry and theft from the cabin or boot - and, in the case of keyless ignition systems, theft of the vehicle itself.
Thanks to its 100% signal jamming capability, faraday bag can completely isolate your fob to make such attacks impossible - giving you complete peace of mind as a protector against data loss.
How does the faraday bag work?
Our faraday bags make your cars safe by stopping signals sent or received by your key fob or any other device containing data.
Remove your key from the faraday bag and signal reception is restored immediately, enabling normal usage.
Attention:
1 . Please make sure your vehicle key fob is put in to inner layer since only the Inner layer blocks signals.
2 . Please do not wash the faraday bag; keep the interior dry, or it may lose signal-blocking function.
